The answer

Normandy, France · FR

How the AI detective did

The AI placed its guess 331 km from the real location (it guessed St Michael's Mount, Cornwall).

With the full clue set, the AI recognized a tidal-island abbey — but committed to St Michael's Mount in Cornwall, Mont Saint-Michel's English twin.

The evidence the AI read

• architecture: A stone abbey rises above compact medieval buildings on a tidal island. — This points to a historic coastal monument in western Europe.
• terrain: Wide tidal flats surround the settlement rather than open ocean cliffs. — The site is likely on a bay with extreme tides.
• climate: Low sunrise light and bay weather suggest a temperate maritime climate. — Northern or western France is plausible.
• era_marker: The image quality and tourist-site lighting are contemporary. — A 2020s capture is more likely than an archival photograph.
